In this paper, we show a class of relationships which link Discrete Cosine Transforms (DCT) and Discrete Sine Transforms (DST) of types V, VI, VII and VIII, which have been recently considered for inclusion in the future video coding technology. In particular, the proposed relationships allow to compute the DCT-V and the DCT-VIII as functions of the DCT-VI and the DST-VII respectively, plus simple...
Emulation test beds are increasingly used to study the Internet. In this paper we briefly review various characteristics of a test bed based on the Emulab software that are necessary to conduct scientifically rigorous experiments: experiment fidelity and repeatability as well as measurement accuracy and interference. Our results indicate that the current trend of using emulation test beds is justified...
Studying the resilience of complex systems and Critical Infrastructures (CI), e.g., the Internet, in order to improve protection and response mechanisms is an important research activity due to their vital role in modern economy and society. Such studies are frequently based on experimentation using a) real systems, b) software simulation or c) hardware emulation. In this paper we present how our...
